IIVIPROVEMNT IN PICK-HANDLE.

The Schedule referred -to in these Letten Patent and xakng part of thesame..

To It whom it may concer-n Bc it known that I, FRANKLIN Bnmaxcnn,otLockport, in the county of Niagara and State ot' New York, have'invented a new and improved Mill-Pick Handle; and I do hereby declarethat the following is a full, clear, andexact description thereof, whichwill enable others skilled in the art to ina-ke and use the saine,reference being had to the accompanying drawings tin-ming part of thisspecification.

This invent-ion relates to improvements in handles` for mill-picks; andconsists in a handle composed of two parts ot metal dividedlongitudinally, connected at the end to bc taken in the hands, and atshort distance from the other end, the two parts ot' which are madecapable ot' springing between the latter connection and the ends, whichare ttted to pass through an eye'in the pick and to be-wedged againstthe side walls of the eye by a long steel or other metal wedge runningthrough the handle from end to end, in grooves in the two parts of thehandle, which form a central -hole when the said two parts are connectedt0- gether. v

By another arrangement the handle may be made in one piece, and'split orbifurcated at the end for entering the eye of the pick to form thesprings.

The shouldered part against which the pick is received is arranged forthe attachment of weights, to

be used when the picks are light, and the part to be taken in the handsis reduced, and a tube of wood or other light and suitable substance isplaced on it and held by a nut or other means.

Figure 1 is a longitudinal section 'ot my improved handle with the pickattached, and

Figure 2 is a partial longitudinal section taken in a plane at rightangles to that of iig. 1.

Similar letters ci' reference indicate corresponding parts.

A represents one of the metallic parts of the handle, to be made bycast-ing or otherwise, and provided with a groove in the center of theface fitting the. other half, which is the counterpart 0f A.

Eachpart is reduced in thickness-from the point B /to C, so as to becapable-of springing, and the endsD are madebroad and thin, to beengaged with eyes in the center of the picks. l

They are groovcd or recessed at E, where they bear against the innerwalls of the eyes, to hold the picks Gr more firmly, and fitted also forthe reception of the blocks or weights F between the pick and theshoulders H.

These two parts are connected together at I by pins, rivets, or screwsK, and at the other end by the nut screwing onto each part.

M is a steel wedge, longer than the handle, placed in the hole formed bythe central grooves in each part, to be driven between the ends D afterthey are inserted in the eye ofthe pick to wedge them ont firmly againstthe walls ofthe eye, whereby the pick will be very securely. attachedina very simple manuel'. The said wedge may be driven either way, tosecure or release the pick, by striking the ends on the stone or otherhard substance.

Instead of making the handle in two parts and counect-ing them together,it may be cast in one piece and split or bifurcated from the point Btoform the springy parts. In this case it would be cast on a core, toform the hole for the wedge M.

The weights F are attached to the two parts D by screws, so as to bereadily detached when not required. They are so shaped and arranged asto appear' to be enlarged shoulders of the handle when attached.

The part of the said handle to be held in the hands is made smaller thanthe other part, and a ferrule or sleeve ot' wood or other light andsuitable substance is placed thereon and secured by the nut L.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- A tubularpick-handle bitul'cated at its lower end, and fastened to the tool bymeans of a wedge,-in the manner shown and described.
